After simplifying my tab-line-tabs-buffer-list-function the issue went
away and hasn't been seen since.

So with regard to the subject of this issue I think it's fine to close
this. Not having tab-line-mode call tab-line-tabs-buffer-list-function
on pretty much every possible event might be a worthwhile improvement
at some point though (I haven't checked whether things improved in
Emacs 28).
